Post From: Platform Freezing on Startup

I’m once again having the same/similar issues since re-installing the platform per steps taken, yesterday, in post #16.

See below for all iterations performed to narrow down the culprit.

FINDINGS

- Enabling Custom symbol settings is the root cause.
- w/ Custom symbol settings enabled ESU26 is an idiosyncratic problem, at least for me.

BAND-AID

- Turn OFF Custom Symbol settings prior to exiting the platform each time.

QUESTION

- Is this something you will investigate further or should I only let you know if my “band-aid” stops working?




ITERATIONS

(1) NO JOY: Startup causes main instance to go into “Not Responding” before loading any market data

- Custom Symbol Settings are ON (my only purpose for enabling is so I can set a Trade Position Limit).
- Main instance is Set to run instances 2,3.
- Main Instance is set to open files consisting of 1 chartbook with Trade DOMs for [CBV][M] of ESU26, CLQ26, GCQ26, ZNU26, ZTU26, 6EU26, 6BU26
- Instance 2 is set to open files on startup consisting of 1 chartbook ([CBV][M] ESU26 ) that is the same chartbook attached in post #15, WITH the addition of [CVB][M] DOMs for MESU26 and ESU26.
- Instance 3 is set to open 2 chartbooks ([CBV][M] CLQ26, GCQ26) that are the same layout as the "10_0101_ES" chartbook attached in post #15 (these CL,GC chartbooks do NOT have DOMs).

(2) SUCCESS: Startup works correctly

- Turn OFF Custom Symbol settings
- All other settings from iteration (1) remain the same.

(3) SUCCESS: Startup works correctly, BUT prior to Exit of Iteration (2)
  
– Turn ON custom symbol settings
– Turn OFF open files on startup for Main Instance chartbook (i.e. all Trade DOMs).
– Turn OFF open files on startup for instance 2 Chartbook ESU26 w/ MESU26 and ESU26 DOMS from Iteration (1)
– All other settings from iteration (2) remain the same

(4) SUCCESS: Startup works correctly, BUT prior to exit of Iteration (3).

- Leave custom Symbol Settings ON
- Delete only ESU26 DOM in Main instance chartbook.
- Turn ON Main instance to open files on startup for its Trade DOM chartbook (that no longer has ESU26 DOM).
- But turn OFF open files on startup for instance 2 ("10_0101_ES" chartbook).
- All other settings from iteration (3) remain the same

(5) NO JOY – while platform is still open from iteration (4)

- Open instance 2 ("10_0101_ES") chartbook, with the added MESU26 and ESU26 DOMs with the following result
RESULT
- Instance 2 chartbook opens, charts load and remain functional, HOWEVER
- MESU26 DOM only loads top level of book and allows orders to be placed, BUT the ladder is frozen and last trade price does not update.
- ESU26 DOM also loads top of book BUT no orders can be placed and ladder is also frozen
- Instance 3 charts remain functional (there haven’t been any DOMs in instance 3 at any point.).
- Main instance freezes after chartbook trade DOMs were running fine prior to instance 2 chartbook being opened.

(6) SUCCESS: Repeat iteration (4) after having done an “end task” to close Sierra after Iteration (5)

- Custom symbol settings are STILL ON.
- In Main instance: copy MESU26 DOM and change symbol of DOM copy to ESZ26 (December) contract.
- Result DOM loads and works fine.
- Turn OFF Custom symbol settings and open existing front month chartbook ESU26 (September) in Instance 2.
– Result, chartbook charts AND the MESU26 and ESU26 DOMs open and function correctly.

(7) SUCCESS: Prior to exiting after iteration (6)

- instance 2 chartbook “SaveAs” new chartbook AND
- change Chart and DOM contracts to the DECEMBER contract MESZ26 and ESZ26.
